For 2014 I will be riding a nice handmade steel 29er by a local compagny named XPREZO. They are a small business here in Canada, welding their frame in house, painting, etc. They are a small bunch of passionate guys and im looking foward to working with them as a rider.

I've got my frameset yesterday, a nice T-29, 29er hardtail built with Columbus Zona tubes. The nude frame (before painting) weights 1600g in medium size. My frame weighted in at 2002g including the pressfit GXP bottom bracket and the lower headset fitting. It has a race geometry and a rear 142x12mm axle.

I thought a canadian handmade steel 29er would be somewhat exotic so I plan on updating my thread as the build progresses. I may need some of the valuable weight-weenie help with regard to affordable and light parts. I already got a good bunch of parts and they are not the lightest but they are reliable. My first concern is reliability because I am training and racing a lot on my bike. My target weight would be 10,5kg though im not sure I can reach that goal with the current parts I have and intend to use for this build.

Of course there are plenty of photos to come with weights and scale shots

The required headset is 44mm and the bottom part of the head tube does not have that groove to sit the bottom bearing like in carbon frame. My question related to that: do I absolutely need to use a headset with a lower fitting like mine or can I somehow use something that looks fully integrated? I guess I could shorten the HT by 3-5mm that way.

You can run an internal bottom cup which is just a completely normal zero stack headset, but then you have to run a fork with a straight steerer - the taper is too large to fit, no way of having both with your headtube.

Tune don't currently make a headset to suit tapered forks in 44mm headtubes AFAIK.

The frame weight is pretty good for what it is and definitely a fair bit lighter than something comparable, like a Niner. It's also heaps lighter than the errr, more entry level stuff from On One, Surly, Salsa etc

My main concern was the bottom external cup, since I absolutely need one, I'll keep the current headset. I already have the ultrastar 2

The stock seatpost clamp is 25g, I need something lighter but it has an uncommon diameter of 30mm. I know the cannondale EVO would fit, I think... Any other light options out there? Some more marginal saving!

You realise the weight saving can be pretty big on the headset right? For example, even with the heavy duty top bearing the Extralite weighs less than half as much as something like a King yet costs about the same? Someone could save as much as 100 grams using the Extralite headset over an average OE unit. Your FSA would probably be at the heavier end of the spectrum too.

great frame, two of the guys on my university team were riding those this season, both in black with lime graphics (one matte one gloss). Really solid bikes, I got to demo one during the summer when Antoine came down to the shop i work at. Fast, but didnt like being in the air, maybe that was just the way it was set up, but that was my only qualm with the bikes. Such a great finish on them, I love steel bikes so much!
